Question
Which of the following reactions increases production of dihydrogen from synthesis gas?
Options
\[\ce{CH4 (g) + H2O (g) ->[1270 K][Ni] CO (g) + 3H2 (g)}\]
\[\ce{C (s) + H2O (g) ->[1270 K] CO (g) + H2 (g)}\]
\[\ce{CO (g) + H2O (g) ->[673 K][Catalyst] CO2 (g) + H2 (g)}\]
\[\ce{C2H6 + 2H2O ->[1270 K][Ni] 2CO + 5H2}\]

Solution
\[\ce{CO (g) + H2O (g) ->[673 K][Catalyst] CO2 (g) + H2 (g)}\]
Explanation:
The production of dihydrogen can be increased by reacting carbon monoxide of syngas mixtures with steam in the presence of iron chromate as catalyst.
